It's the tty device that you failed to get the icount for, not the LED device, so you just confused the user by saying that a LED now can not get tty data :) > mutex_unlock(&trigger_data->mutex); > return; > } > @@ -126,8 +127,7 @@ static void ledtrig_tty_work(struct work_struct *work) > icount.tx != trigger_data->tx) { > unsigned long interval = LEDTRIG_TTY_INTERVAL; > > - led_blink_set_oneshot(trigger_data->led_cdev, &interval, > - &interval, 0); > + led_blink_set_oneshot(led_cdev, &interval, &interval, 0); This is fine, but not needed if you fix up the above change. thanks, greg k-h
